618,6 WITNESSES INVENTOR fill/9L. Gue/zf/zer By W ATTORNEYS naled in suitable bearings on the main frame A. On the shaft K is secured a detent wheel K provided with four notches K adapted to be enga ed successively by friction rollers L and L ournaled on the outer ends of an arm L secured on a shaft N journaled in suitable bearings arranged on the main frame A. On the shaft N is secured a gear wheel N in mesh with a pinion N secured on the cam shaft I so that the latter trans mits a continuous rotary motion to the shaft N which by the arm L and the friction rollers L, L imparts an intermittent rotary motion to the detent wheel K and consequently the shaft K, and this intermittent rotary motion of the shaft K is transmitted by the pinion B and the gear wheel 13' to the carrier shaft B. On the shaft N is secured a locking disk L adapted to engage segmental recesses K in the peripheral face of the detent wheel K to lock the latter against accidental turning after the friction roller L or 'L is moved out of engagement with a corresponding recess K of the detent wheel K and until such friction roller L or L engages the next following recessK. The transmission as described is so proportioned that at each revolution of the cam shaft 1 the carrier shaft B is given one-eighth of a turn with the carrier C at rest at the time that the top seat C is in register with the clamp F, the next following seat to the right being in register with the delivery chute E, as indicated in Fig. d.

in order to impart an intermittent up and down movement to the clamp F, the following arrangement is made: The up er end of the clamp F is pivotally connecte by a link F with an arm F secured on a shaft F journaled in suitable bearings arranged on the main frame A, and on the said shaft F is secured an arm F connected by alink F with one arm of a. bell crank lever F (see Fig. l) carrying at its other arm a friction roller F engaging a cam groove F in one face of a cam F secured on the cam shaft l and rotating with the same. By reference to Fig. 4 it will be noticed that the cam groove F is shaped in such a manner that a downward movement is given to the clamp F during a portion of one revolution of the cam shaft 1, and then the clamp F is held stationary in clamping position on the top can body D for another period of one revolution of the shaft 1, and then the clamp F is moved upward during the remaining ortionof the one revolution of the cam s aft I. The clamp F is held stationary during the time the dies G and G enter the ends of the can body and form flanges thereon, and then return to outermost position after which the clamp F is raised as above described.

In order to impart an intermittent reciprocatingmovement to the dies G and G, the following arrangement is made, special refshoulder G of each die erence being had to Figs. 2, 3 and 5: The dies G and G are provided with spindles G Gr terminating in reduced threaded ortions G and G screwing in cross head O and O mounted to slide longitudinally in uideways A A arranged on the main rame A. By the arrangement described the dies G and G can be adjusted lengthwise in the cross heads 0 and 0 so as to move the inner or opposite faces of the dies G, G in proper position relative to the ends of the can body D to be flanged at the time. It is understood that this adjustment is necessary to flange can bodies of different length. Lock nuts G, G screw on the threaded portions G, G to lock the dies G and G against accidental movement after the desired adjustment has been made. The outer ends of the cross heads 0 and O are pivotally connected with toggle mechanisms 0 O fulcrumed at O, O on the main frame A. The said toggle mechanisms O are pivotally connected by links l and l with slides P P mounted to slide vertically in suitable guideways A and A arranged on the main frame A, as plainly indicated in Fig. 5. I The lower ends of the slides P, P are connected by links P, 1 with levers Q, Q, fulcrumed at Q Q on the main frame A. The levers Q and Q are provided at their outer ends with friction rollers Q, Q, engaging cam grooves Q, of which one is formed in one face of the gear wheel I and the other is formed in one face of a cam Q secured on the cam shaft 1. When the cam shaft I is rotated an intermittent reciprocating movement is given to the dies G and G by the mechanism just described so that the inner ends of the dies G and G pass into the ends of the can body D and form the flanges l) thereon. Each of the dies G and G is provided at its inner face with a reduced portion G and shoulders G, of which the reduced portion G has a tapering or a conical outer portion so as to permit the reduced portion G to readily enter a corresponding open end of the can body D, each of which finally comes in contact with the shoulder G to turn the said edge outward with a view to form the flange D on the corresponding end of the can body D, as will be readily under stood by reference to Fig. 6. if desired, the

i or G may be provided with an overhang G (see Figs. 8 and 9) to limit the width of the flange 1) formed on the can body D The chute E is made adjustable to accommodate can bodies D of different length, and for this purpose the following arrangement is made, special reference being had to Figs. 1, 2, 3 and 4. -The chute E consists of two side pieces each formed of two angle irons E, E connected with each other by a side plate E and to the outer faces of the angle irons E, E of each side piece is secured a supporting bar E adjustably held on screw rods E attached-to brackets E secured to the main frame A. On each screw rod E screw pairs of nuts 13 ,15 between which extends, the corresponding supporting bar E, and by adjusting the nuts E, E the supportin bars can be adjusted to move the side pieces of the chute E toward or from each other according to the length of the can body D to be flanged at the time. It is understood that the angle irons E, E are spacedapart' a distance corresponding to the outside diameter of the can body, and the side portions have their lower portions inclined inwardly and downwardly to direct the can bodies toward the carirer C, as ,will be readily understood by reference to Fig. 4. The inner end of the chute H is provided with an upwardly and inwardly extending tongue H reaching between the two Wheels forming the carrier C to engage a flanged can body and move the same out of its scat C and onto the chute H. I

The operation is as follows: When the machine is running and the several parts are in the position shown in Fig. i, then the lowermost can body in the chute E is seated in the seat C of the carrier C while a previously introduced can body is in uppermost position on the carrier C and is engaged by the clamp F. At this time the dies G and G are moved toward each other so that the terminals G pass into the projecting ends of the top can body D to form the flanges D thereon, and then the dies G and Gr move out of the ends of the flanged can body back to their original position, after which the clamp F is raised and hence moved out of engagement with the flanged can body. A turning motion in the direction of the arrow a is now given to the carrier C to move the latter one-eighth of a revolution, so that the previously introduced can body now moves into uppermost positiornand another can body passes from the chute E into the seat C now in register with the lower end of the chute. The clamp F now moves downward into clamping engagement with the uppermost can body 1), after which the dies G and G are again moved inward to ward each other, and the above-described operation is repeated. At the next turning movement given to the carrier C the can body first flanged is moved out of its seat by the tongue Hand directed onto the chute H which carries the flanged can body away from the machine.

Having thus described my invention, 1 claim as new and desire to secure by'Letters Patent:
